of catching wild-fowl will before long have passed out of use. The 
accounts of holidays spent on the Broads in summer, in a little centre- 
hoard yacht, are very tempting, and will, we fancy, lead many to follow 
the author’s example. W. J. H. 
Phillips's Manual of Geology. Yol. I. Physical Geology and Palaeon¬ 
tology. By H. G. Seeley, F.R.S. 8vo., 516pp., 147 woodcuts and 
coloured plate. Price 18s. C. Griffin and Co. 
The last edition of Prof. Phillips’s valuable work was published in 1855, 
and the progress of science since that date has been so great that the 
book, the title of which appears at the head of this notice, is practically 
a new work. It is a work on which Prof. Seeley has expended great 
labour, and from a careful study of its contents we can say that it will 
prove a most valuable book of reference for students of geology—British 
geology especially. The introductory chapters deal with the origin of 
geology and the earth; minerals have one chapter allotted to them, 
while rocks require four. Volcanic rocks—ancient and modern—are 
treated of in great detail, while the chapters on “ Coast Lines and their 
Origin,” and on the “Relation of Scenery to Geological Phenomena,” 
are of great interest for even the general reader. Two chapters are 
devoted to an introduction to Palaeontology. Those who know the 
valuable work which Prof. Seeley has done at Cambridge and in 
London, together with the ripeness and catholicity of his knowledge, 
will be pleased to possess this book, which contains much that is both 
new and true, while the old truths on which the science of geology 
rests are set forth with simplicity and accuracy. The illustrations are 
well conceived and telling. W. J. H. 
THE MICRO-VEGETATION OF BANK NOTES.* 
The recent researches of Paul Reinscli in Erlangen have revealed 
the occurrence, on the surfaces of the coins of many nations, of different 
bacteria and two minute algae (Cliroococcus monetarum and Pleuro- 
coccus monetarum, P. Reinscli), living in a thin incrustation of organic 
detritus composed especially of starch-grains, fibres, &c., deposited 
upon their surfaces during the course of long circulation. This thin 
incrustation renders the coins very suitable for this micro-vegetation, 
but the same phenomenon is exhibited by paper money, and, indeed, 
by notes of clean and, to the naked eye, unaltered surface. 
I have scraped off some of these minute incrustations with hollowed 
scalpels and needles, and divided them into fragments in distilled 
water that had been boiled shortly before, and, upon examining them 
with lenses of high power (R. T. Beck’s 1-lOtli inch), have seen the 
various Scliizomycetes distinctly.
